Only one of four burners will light.

We have a CharBroil model 463453206 gas grill using liquid propane. After lighting the first burner (first of four) using the electronic igniter, then when we try to turn on the second burner it does not light even though we think we can hear additional gas going to it. We are also unable to light the third and fourth burners. What can we do?

Hello,
there is a carry over tube between the burners that looks like a burner hold down at the
back of the grill. This is likely rusted closed and will need to be
cleaned or replaced. The clips that hold the tube down are part #
7000132 and the tube part # is 7000280. They can be purchased directly
from Char-Broil or Sears parts. http://www.charbroil.com/http://www.searspartsdirect.com

If you smell gas, don't attempt to light the burner. Instead, turn the gas off and inspect the fuel tank, lines and burners once the smell of has has cleared. Always grill where you have adequate ventilation and perform all repairs only after the grill has fully cooled from use.home lights

Before buying anything, look into the burners for spider webs. The webs block gas from getting to the burner and will fire back. This is dangerous. Look carefully where the gas nozzle enters the burner tube.

The problem is more than likely the OPD Valve in the gas tank. To solve this problem, turn the Tank Valve OFF and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Turn the tank valve ON VERY,VERY SLOWLY (Slow motion, slow). Once it's fully open, light the burner farthest from the tank first and turn it to it's highest setting. Does the flame height look correct? If so, light the remaining burners following the same procedure. Now, to all the flame heights look correct? If so, you solved the problem. Just remember to always turn the tank valve ON very, very slowly. If it didn't solve the problem, make sure you have adequate gas in "old propane tank from the other grill."

Hello,You may have a rusted, clogged or
damaged burner or venturi tube. With a flashlight, check for spider
webs, wasp nests or dirt (mud) dauber nests in the opening of the
venturi tube where it connects at each gas valve orifice. Clean it out
manually or blow it out with air compressor. Make sure the air
adjustment opening (on the end of the burner's venturi tube) has not
been changed. If it's closed too much, it will be difficult to light and
cause lazy yellow flames. If it's not clogged, the burner may just be
old and rusted and the burner holes are not allowing very much gas
through anymore. It's also possible the burner has rusted so bad, the
burner holes have been enlarged, it is falling apart or has cracks along
the burner seams. If so, replace the burner(s) immediately. It is
unsafe to use. Your local propane co can usually order the parts you
need and some will even do the work, if you are uncomfortable doing it
yourself. Bring with you the Make, Model and Serial number of the grill,
so they can order the correct parts for your specific grill. Also
specify whether it's natural gas or
propane.Douglas

This problem can be caused by a number of things. Is this a new grill? If not, is this a new problem?

First -Check to see if the fuel hose is bent or kinked.
• Make sure the grill area is clear of dust.
• Make sure the burner and orifice are clean.
• Check for spiders and insects.
• The regulator has a safety device that restricts the flow of gas in the event of a leak. This safety device can be triggered without a gas leak. To reset the safety device, turn all burners "OFF" and close the Liquid Propane cylinder valve. Disconnect the regulator from the Liquid Propane cylinder and wait 1 minute. Reconnect the regulator to the Liquid Propane cylinder and slowly open the valve until the valve is fully open. Light all burners and observe the temperature.
